We've never had concerns about being compared to anyone else. First experience was automatically "the best ever". Subsequent experiences continued (continue) to get even better with the same person.
Knowing our mutual commitment allows comfort about the present and future.
Environment of comfort, trust, and lack of comparison relaxes the situation which has been demonstrated to improve the experience between partners as well.
As we both continue to keep it we protect ourselves and our family from one of the greatest threats to our marriage and family.
The Law of Chastity is awesome for realtionships if you both keep it.
